At what height the gravity is half of the gravity on Earth's surface
Answers
Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth's radius - (9.8 m. s−2 per 3,200 km.)
Newton's Universal Law of Gravitation: Newton's Universal Gravitational Law states that ''Every particle of matter in the universe attracts every other particle with a force, which is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them...''
The Universal Gravitational Constant 'G': The Universal Gravitational Constant is equal to the force of attraction between two point masses of 1 kg each kept at a distance of 1 metre apart...
The Force of Gravity: If out of the two masses, one is the Earth(or any other planet), then the gravitational force is said to be the Force of Gravity...
